Answer:
Step-by-step explanation:
Hi there!
The equation of the line is written in slope-intercept form (y=mx+b)
m is the slope, and b is the y-intercept.
So, we can identify the slope pretty fast, just by looking at the equation.
y=7x+4
Slope (gradient)=7
Thus, is our final answer.
Hope it helps! Enjoy your day!

Answer:
Step-by-step explanation:
Cost of first 4 kilometers ride = 11 pesos.
So, for the first 4 km, the fair is constant i.e.
for 1 km the fare is 11 pesos,
for 2 km the fair is also 11 pesos,
similarly, for 3 km of 4 km, the fare is 11 pesos.
Hence, for the distance , the fair function,
After 4 km, there is an increment of $ 3.50 for each kilometer.
So, the fare function up to 5 kilometers,
So, the fare function up to 6 kilometers, i.e for the distance ,
This can be arranged as the fare function up to 6 km,
Similarly, the fare function up to kilometer
,
Hence, from equations (i) and (ii),
